スプリングを使ったbean工場

public class MainClass {
    public static void main(String[] args) {
    //   spring  bean  
    BeanFactory factory = new ClassPathXmlApplicationContext(
    "applicationContext.xml");

    IMessage msg = (IMessage) factory.getBean("msg1");

    //      bean  
    msg = MessageFactory.create("2");

Spring依存注入の基本的な方法
セット方法注入例UserManager.java

public class UserManager {
    //   set    
    private String driverCalss;
    private String url;
    private String username;
    private String password;

    public void addUser() {
        System.out.println(this.toString());
        System.out.println("    _    ！");
    }

    public void setDriverCalss(String driverCalss) {
        this.driverCalss = driverCalss;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    @Override
    public String toString() {
        return "UserManager [driverCalss=" + driverCalss + ", url=" + url
        + ", username=" + username + ", password=" + password + "]";
    }
}

UserAction.java

public class UserAction {
    private UserManager manager = null;

    public void setManager(UserManager manager) {
    System.out.println("    manager set    ！");
    this.manager = manager;
    }

    public String execute() {
    this.manager.addUser();
    return "success";
    }
}

spring配置ファイル:appication Contact.xml

MainClass.java

    public static void main(String[] args) {
    
        //   spring  bean  
        BeanFactory factory = new ClassPathXmlApplicationContext(
                "applicationContext.xml");
        // BeanFactory factory = new ClassPathXmlApplicationContext("app*.xml");
    
        UserAction ua = (UserAction) factory.getBean("userAction");
        System.out.println(ua.execute());
    }

Scrope属性とBenFactoryAwareインターフェース
UserManager.java

public class UserManager {

    //   set    
    private String driverCalss;
    private String url;
    private String username;
    private String password;

    public void addUser() {
        System.out.println("    _    ！");
    }
    //  set get  
    ……
}

UserAction.java

/**
*     BeanFactoryAware
*/
public class UserAction implements BeanFactoryAware {
    private UserManager manager = null;

    public void setManager(UserManager manager) {
        // System.out.println("    manager set    ！");

        this.manager = manager;
    }

    public String execute() {
        //             bean      ，    
        // BeanFactory factory = 
        //      new ClassPathXmlApplicationContext("applicationcontext.xml");

        //                   ：
        //        
        manager = (UserManager) factory.getBean("userManager");

        System.out.println(manager);
        this.manager.addUser();
        return "success";
    }

    BeanFactory factory = null;

    @Override
    public void setBeanFactory(BeanFactory factory) throws BeansException {
        // TODO Auto-generated method stub
        this.factory = factory;
    }
}

appication Contect.xml

MainClass.java

public static void main(String[] args) {
    // UserAction userAction = new UserAction();
    // UserManager manager = new UserManager();
    // userAction.setManager(manager);

    //   spring  bean  
    // BeanFactory factory = new ClassPathXmlApplicationContext("app*.xml");
    BeanFactory factory = new ClassPathXmlApplicationContext(
            "applicationcontext.xml");
    UserAction ua = (UserAction) factory.getBean("userAction");
    System.out.println(ua);
    System.out.println(ua.execute());
    
    ua = (UserAction) factory.getBean("userAction");
    System.out.println(ua);
    System.out.println(ua.execute());
    
    ua = (UserAction) factory.getBean("userAction");
    System.out.println(ua);
    System.out.println(ua.execute());
}

id_name_ref(bean、local、parent)などの属性の使い方

MainClass.java

    /**
     * BeanFactory factory = new
     * ClassPathXmlApplicationContext("applicationContext02.xml");
     * 
     *  factory     （    ）
     * BeanFactory fay = new XmlBeanFactory( newClassPathResource(
     * "applicationContext.xml"), factory );
     */

セットメソッドに集合属性を注入する
UserAction.java

public class UserAction {

    public List list = null;
    public Set set = null;
    public Map map = null;
    public Properties props = null;

    public void setList(List list) {
        this.list = list;
    }

    public void setSet(Set set) {
        this.set = set;
    }

    public void setMap(Map map) {
        this.map = map;
    }

    public void setProps(Properties props) {
        this.props = props;
    }
}
